Abstract
The utility model discloses a kind of new structure safety check, comprise valve body, auxiliary valve body, spool, spring and overcurrent guide sleeve, valve body and auxiliary valve body are straight-through type valve body, be threaded connection between valve body and auxiliary valve body, spool is arranged in valve body, after valve body and auxiliary valve body assemble, auxiliary valve body is screwed into part in valve body by overcurrent guide sleeve fixing and locking between valve body and auxiliary valve body by screw thread, spring is arranged between overcurrent guide sleeve and spool, is provided with O RunddichtringO between valve body and auxiliary valve body.New structure safety check in-site installation of the present utility model is convenient, and standardized designs is avoided wasting material, easily realizes volume production; The area of passage of overcurrent guide sleeve and the area equation of valve flowing channel, avoid conventional construction partial throttling and wash away serious, the problem that valve working life is short; The preferred nickel-bass alloy material of spring, corrosion resistance and good, and the spring in straight-through type valve body only has reset response, medium low-pressure is opened, and the pressure loss is little.
Description
Technical field
The utility model belongs to valve technology field, relates to a kind of new structure safety check specifically.
Background technique
Safety check is also known as one-way valve or check valve, its effect ensures medium directional flow in pipeline and can not flow backwards, it is a kind of valve controlling pipeline internal medium single flow direction, belong to automatic valve, be mainly used on the pipeline of medium one-way flow, it allows medium to flow to a direction, and to try to avert accidents, the Applicable media of usual safety check is water, oil product, steam or acid medium etc.In prior art the safety check of conventional construction have structure more complicated, not easily realize volume production, not easily install, the shortcoming such as the corrosion resistance of contained spring is poor, and safety check of the prior art due to structural design unreasonable, make the working life of safety check shorter, also the frequent problem that there is seal failure because of the sealing face damage of conical surface seal.Simple, reasonable in design, easy for installation, the long-lived new structure safety check of a kind of structure how can be provided to become the urgent demand of people.
Summary of the invention
The deficiency that the utility model exists to overcome prior art, provides a kind of structure simple, reasonable in design, easy for installation, long-lived new structure safety check.
The utility model is achieved through the following technical solutions: a kind of new structure safety check, described new structure safety check comprises valve body, auxiliary valve body, spool, spring and overcurrent guide sleeve, described valve body and described auxiliary valve body are straight-through type valve body, the internal surface of described valve body connecting end is provided with internal thread, the outer surface of described auxiliary valve body connecting end is provided with outside thread, be threaded connection between described valve body and described auxiliary valve body, described spool is arranged in described valve body, after described valve body and auxiliary valve body assemble, auxiliary valve body is screwed into part in valve body by described overcurrent guide sleeve fixing and locking between valve body and auxiliary valve body by screw thread, described spring is arranged between described overcurrent guide sleeve and described spool, O RunddichtringO is provided with between described valve body and described auxiliary valve body.
The outer end of described valve body and described auxiliary valve body is hexagonal structure, the size of described hexagonal structure and the measure-alike of standard wrench.
The area of passage of described overcurrent guide sleeve and the valve flowing channel area equation of safety check.
Described spring is the corrosion-resistant spring be made up of nickel-bass alloy material.
Fire-protection ring is provided with between described valve body and described auxiliary valve body.
It is plane sealing structure between described spool and described valve body.
The beneficial effects of the utility model are: the auxiliary valve body 1, innovated and valve body configuration design, and the size of hexagonal structure presses standard wrench size design, and in-site installation is convenient, and standardized designs is avoided wasting material, easily realizes volume production; 2, the flow-passing surface of overcurrent guide sleeve is through optimal design, the area equation of area of passage and valve flowing channel, avoids conventional construction partial throttling and washes away serious, the problem that valve working life is short; 3, the preferred nickel-bass alloy material of spring, corrosion resistance and good, and the spring in straight-through type valve body only has reset response, medium low-pressure is opened, and the pressure loss is little; 4, spool and valve body adopt plane sealing structure, and sealing is reliable, avoids sealing face damage and the seal failure problem of conical surface seal; 5, valve body and auxiliary valve body adopt and are threaded, and overcurrent guide sleeve is just in time fixed by the part that the rear auxiliary valve body of assembling is screwed into valve body, avoid conventional construction not have locking mechanism to cause overcurrent guide sleeve to loosen because pipeline shakes, the problem that valve performance changes.
